Can you Export (from your unnamed screen-cap program) as a DV-AVI Type II? I do not know TSCC, but Cinepak is a very old CODEC. If you need something beyond NTSC/PAL DV, you might want to look to an intermediate CODEC, like Lagarith, which is free. Just having a CODEC to Export to does not mean that PrPro will play nice with that CODEC. Some are much, much better choices. What choices does your program offer, besides TSCC & Cinepak?
